15x-6=-90
explore how the values of algebraic expressions like100-x,5/x+5,and
(3y) / (2y) change as the values of the variables change.
F(x) = 5x
for f(7) you replace x with 7 so it will be : f(7) = 5(7) = 35
I'm pretty sure the answer to this is x=65 but I could be wrong.Not very good with this kinda Algebra.
Answer: Cost of tickets for adults = $22
Cost of tickets for children = $15
Total number of tickets sold = 732
Total receipts = $12,912
Let x be number of adult ticket's sold and y be the number of child ticket's sold.
Therefore, we have:
--------------- equation 1

Also, we have:

Now, let's substitute the value of x:






Now, let's substitute the value of y=456 in equation 1, we have:



Therefore, the number of child ticket's sold is 456 and number of adult ticket's sold is 276
